Quotes, progress invoices, withholding tax and recurring subscription billing.
Service work has no stock, but it is usually billed in stages: you quote, then invoice as the work progresses. In construction, withholding tax also comes in and the amount to collect differs from the invoice total.
In Kumpara a quote becomes an order, and the order can be split into partial invoices. Withholding applies to the whole invoice or to individual lines, and the payable amount is shown correctly. Monthly maintenance or subscription invoices are prepared as drafts on schedule — you only review and approve.
